Gold is special not just for its looks, but also its properties. Just 3 g of gold can be beaten out to form 1m2 of gold leaf approximately 1.8 x 10-7m thick. By comparison, a US dime has a thickness of approximately
1.35 x 10-3m. How many sheets of gold leaf would you need to create a stack the same height as the dime?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
